Crystal kua yog ib yam khoom tshwj xeeb ntawm cov khoom thiab cov kua. Nws yog ib qho organic compound uas yog kua nyob rau hauv ib txwm muaj mob, tab sis nws cov kev npaj molecular yog tsis tu ncua zoo li cov khoom siv lead ua. Yog li ntawd, nws yog hu ua kua crystal. Nws yog lwm qhov tshwj xeeb Qhov xwm yog tias yog ib qho hluav taws xob siv rau cov kua siv lead ua kua, nws qhov kev hloov pauv ntawm molecular yuav raug hloov. Nyob rau lub sijhawm no, yog tias nws sib phim nrog lub polarizer, nws muaj qhov cuam tshuam los tiv thaiv lub teeb los ntawm kev hla. Niaj hnub no, cov ntxaij vab tshaus LCD tuaj yeem pom txhua qhov chaw hauv lub neej, xws li laptops, LCD TVs, xov tooj ntawm tes, SLR koob yees duab, thiab lwm yam. Niaj hnub no, LCD cov ntxaij vab tshaus tau dhau los ua cov khoom siv hluav taws xob yuav tsum muaj rau ntau tus neeg. Yog li dab tsi yog qhov txwv tsis pub siv cov ntxaij vab tshaus LCD? Tus editor Zhilingxin hauv qab no yuav qhia rau koj.
Dab tsi yog qhov contraindications thaum siv lub vijtsam LCD:
1. Moisture ntxeem tau
Cov dej noo tuaj yeem hais tau tias yog thawj tus yeeb ncuab ntawm cov kua siv lead ua kua. Lub zog puas tsuaj ntawm dej ntawm lub vijtsam LCD yog qhov tsis txaus ntseeg. Yog li ntawd, lub vijtsam LCD yuav tsum tau siv nyob rau hauv ib qho chaw qhuav kom tsis txhob ya raws los ntawm kev nkag mus rau sab hauv ntawm lub vijtsam LCD. Rau qee cov neeg siv uas ua haujlwm hauv qhov chaw ntub dej, koj tuaj yeem yuav qee qhov desiccant kom huab cua nyob ib puag ncig LCD qhuav.
2, plua plav tawm tsam
Zoo li CRT, LCD yog yooj yim heev kom tau plua plav.
3. Cov khoom tawv tawv
LCD yog qhov muag muag thiab yooj yim puas (tshwj tsis yog lub iav npo sab nraud). Yog li ceev faj tsis txhob kov lub vijtsam nrog cov khoom tawv thaum siv nws.
4. Kev siv sijhawm ntev
Vim tias LCD tsis yog qhov yooj yim, nws cov pixels yog tsim los ntawm ntau cov kua siv lead ua kua, thiab kev siv txuas ntxiv mus ntev yuav ua rau cov siv lead ua muaj hnub nyoog lossis hlawv tawm. Thaum qhov kev puas tsuaj tshwm sim, nws yog ruaj khov thiab irreparable. Yog li nws yog qhov zoo dua tsis txhob siv nws ntev. Tam sim no ntau tus neeg siv computers nyob online. Rau qhov yooj yim ntawm cov duab, lawv feem ntau tua lub saib ntawm lub sijhawm sib txawv tom qab kaw, uas yuav ua rau lub neej ntawm lub monitor loj heev.
5. Kev tuav tsis raug
Cov kua siv lead ua kua yog qhov muag heev, thiab qhov zoo ntawm cov zaub thiab cov kua siv lead ua kua molecules ntawm cov zaub yuav raug puas tsuaj thaum lub sij hawm kev ua phem ntawm kev txav los yog kev co, uas zoo heev txo cov nyhuv. Tsis tas li ntawd, tsis txhob muaj kev poob siab thiab kev vibrations. Lub vijtsam LCD muaj ntau lub iav thiab cov khoom siv hluav taws xob rhiab heev. Poob rau hauv pem teb los yog lwm yam zoo sib xws muaj zog cua tshuab tuaj yeem ua rau puas tsuaj rau lub vijtsam lossis lwm chav. Qhov taw tes no yuav tsum tau them sai sai rau thaum lub sij hawm thauj mus los, sim muab cov cuab yeej tuab rau cov kua siv lead ua kua, thiab tom qab ntawd nqa nws.
